Close Duplicate Tabs

Here are the benefits of closing duplicate tabs.

Once you install this software, you can close duplicate tabs with the click of a button.

An extension that prunes the clones reclaims memory immediately, giving the browser more headroom for genuinely new pages. Users on 8 GB laptops often see fan noise drop and scrolling become smoother the moment duplicates disappear.

2. Cuts CPU and Battery Drain
Even if a page is sitting idle, embedded ads, WebSockets, and animation frames keep the CPU spiking every few seconds. Multiply that by duplicate processes and background activity can consume 5–10 percent of total CPU time. Closing extras removes redundant JavaScript timers and media queries, extending battery life on portable devices and preventing throttling that slows down all open sites.

3. Keeps Your Place in Long Documents
Duplicate pages can desynchronize scroll positions. You read halfway down an API reference in one tab, accidentally switch to the copy stuck at the top, and waste precious seconds finding the spot again. With only the original tab left open, you never lose your context, and in-page anchors or code examples remain right where you expect them.

4. Sharpens Focus and Reduces Cognitive Load
Neuroscience tells us every on-screen element competes for attentional resources. Ten identical favicons force your brain to perform micro-checks—“Is this the real sheet or the duplicate?”—each time you Alt-Tab. A single authoritative tab eliminates that decision point, letting you jump to the page you want without mental friction. Over a day, those micro-savings compound into noticeably smoother task switching.
